Narcolepsy [Preview]

Although people with the disorder do not fall face-first into their soup as in the movies, narcolepsy is still a mysterious disease. But science has new leads

After hearing the punch line of the joke, the teenager falls to the floor, almost as if actually punched. She remains there, completely unable to move. She hears her parents reassure her friends that they need not worry about her because she will be all right in a few minutes. She is embarrassed and frustrated as the episode continues, and her friends begin to leave. They bid her goodbye, but she is unable to respond. Although she cannot talk or move, she is otherwise in a state of high alertness, feeling, hearing and remembering everything that is going on around her. The episode lasts for five minutes, longer than her typical cataplexies--which often last only seconds--but shorter than her longest episode, which lasted 25 minutes. Then it ends, almost as abruptly as it began. She gets up from the floor, and her everyday life resumes.

Cataplexy, the loss of skeletal muscle tone without loss of consciousness, is one of the defining symptoms of a puzzling neurological disorder called narcolepsy. The cataplectic attacks of narcolepsy are frequently prompted by laughter; other times, embarrassment, social interactions with strangers, sudden anger, athletic exertion or sexual intercourse may trigger an episode.

    Who can help me?
    I have suffered from narcolepsy with cataplexy for 30 years,
    and am now dying of Heart Failure. I am a Disabled Veteram
    from the U S Army because of the vaccine, Gamma Gobuline
    which was the cause of my narcolepsy. The VA stripped me
    of my disablity rating in the early 80s and is now turning a
    deaf ear to my present medical condition and needs.
    I have requested that my case be refered to Dr. Jerome Siegal
    and have gotten nowhere. The VA is now wanting evidence
    that my narcolepsy with cataplexy has caused my Heart Failure and Diabetis. I need Dr. Siegals help ?
